I have many corporate and high-value tenants that do this.We hold advance rent in escrow, and we treat it as a deposit, then we release installment payments when that months' rent is called due. 

Get to know people in the various trades (plumbers, electricians, carpenters, painters, siding installers.)

I just installed gas heating systems in 2 buildings and we’ve probably had to go into each unit 25 times during the course of the install and the inspections that followed.

Updating the interior is costing me $63,000 for demo, installation, and materials.

Pex is also much easier to install and requires less access. 

Reminder:Ground improvements qualify for bonus depreciation.This includes various landscaping.Roads and external parking areas.Sidewalks and pathways.Fences.Utility systems (including the installation or improvements to water, sewage, drainage, and electrical systems).Outdoor lighting.Rec facilities (like playgrounds, sports courts, and swimming pools).And more.It's a big category for depreciation/bonus depreciation that we love.

It really is not hard to install submeters in most cases.
